IMPLEMENTATION

Viewers responsible for this format

A WebAssembly binary contains typed sections that describe code, memory and linking. Anyfile validates the module structure and builds a navigable inspection view without running its start function or imports.

Common question

Is the WASM module executed during inspection?

No. The viewer parses bytes and never calls WebAssembly.instantiate.
